Wine is often associated with the Mediterranean lifestyle, socializing, and enjoying food. However, one question keeps coming up: is wine healthy, and is there a “safe dose” of alcohol? Scientific data are clear on one important message: wine is not a medicine and should not be started for health reasons.
Conclusion from research: a small amount of wine is not associated with higher risk
For most healthy adults, a small amount of wine (up to 1 glass per day) has not been associated with increased risk in studies. However, “neutral” does not mean “protective” — especially because the results are largely based on observational studies (associations), not evidence of causality.
What is best supported by evidence?
- Moderate consumption (≤1 glass/day) is not associated with higher overall mortality.
- Some studies show a lower risk of coronary heart disease, but lifestyle likely plays a significant role, including diet, physical activity, and socioeconomic factors.
- Wine has no protective effect against cancer.
- Resveratrol in wine is present in quantities too small to have a clinically relevant effect.
When should you be cautious or avoid wine?
There are situations in which the recommendation is to reduce or completely avoid alcohol, due to a higher risk of complications or worsening of existing conditions:
- If you notice that it bothers you — reduce or avoid it.
- Atrial fibrillation, as alcohol may trigger episodes in sensitive individuals.
- Uncontrolled hypertension.
- Heart failure, especially with fluid retention, arrhythmias, or interactions with therapy.
- Liver disease.
- Pregnancy and breastfeeding.
- Interactions with medications, including sedatives, anticoagulants, certain antibiotics, and others.
What is the “safe dose” of alcohol?
The most important public health message is that 0 is the most reliable and safest option. If wine is consumed, moderation is key:
- If consumed: ≤1 glass/day.
- Larger amounts increase the risk of atrial fibrillation, hypertension, and cancer.
How to drink wine in the “least harmful” way?
If a person already consumes wine and has no clear contraindications, the following principles reduce risk and help keep intake moderate:
- Maximum 1 glass, approximately 100–150 ml.
- Always with a meal.
- Not every day — take breaks.
- No “weekend compensation” — several glasses at once carry a higher risk.
Practical message for patients
Moderate wine consumption in healthy adults is often not associated with higher risk, but wine is not therapy. If you do not drink alcohol, there is no medical reason to start. If you do drink, keep it to a small amount, avoid episodes of higher intake, and be sure to talk to your doctor if you have arrhythmias, hypertension, heart failure, liver disease, or if you take medication that may interact with alcohol.
